Pelargonium sp. (Pelargonia)

Pelargonium sp., commonly known as pelargonium or geranium, refers to a diverse group of species and horticultural forms native mainly to southern Africa, valued for their varied growth habits, aromatic foliage, and ornamental flowers. Plants may range from compact, upright shrubs to trailing or semi-succulent forms, typically growing from under 1 foot to several feet tall depending on the type. Leaves vary widely in shape and texture, from rounded and lobed to finely divided, often with a distinct scent when touched, while flowers appear in clusters and may be simple or elaborate in shades of white, pink, red, purple, or bi-colored.

Pelargoniums generally prefer full sun to bright light and well-drained soil, with moderate watering and drying between cycles to prevent root issues. Growth rate is moderate to fast under warm conditions, and many types bloom over extended periods, especially in spring and summer. Suitable for USDA zones 9 to 11 depending on species, most are frost-sensitive and require protection below about 32 to 40 F. They perform well in containers, making them widely used for patios, balconies, and indoor growing in cooler climates.
